/4/ m d gl g/ iavd/ Patented Mar. 20, 1945 I TAPE MOI S'IENING DEVICE Application October 9, 1943, Serial No. 505,589 I I 4 Claims. (01. 91,-43)

This invention relates to a device for use in the moistening. of the gummed surface of tape and includes manually adjustable means for permitting the reception of tape either as moistened or unmoistened.

It is the principal object of the invention to provide manually controlled shielding and pressure members which are movable relative to a moistening member in such manner that the shielding and pressure members may be adjusted simultaneously to either a moistening or a nonmoistening position. I

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A preferred embodiment of theinvention is 11- lustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view of the moistening device with tape passing therethrough;

Fig. 2 is a front elevational view of Fig. 1 on an enlarged scale;

Fig. 3 is a vertical sectional view, on a further enlarged scale, of Fig. 2 and showing the device in a non-moistening position; and

Fig. 4 is a view similar to Fig. 3, showing the moistening device in a' tape moistening position.

Referring to the drawing in detail, the moistening device generally comprises a supporting member I0, a capillary slotted tube II, a shield I2, and a pressure member I3. The slotted tube II is secured to the supporting member I in a horizontally disposed position by means of a screw Id, and the shield I2 is pivotally supported thereon so that it will be adapted to rock about the axis of the tube II. A rod I5, also secured to the supporting member I0, is horizontally positioned above the slotted tube II and is adapted to support the pressure member I3 thereon in such manner that the said pressure member will rock about the axis of the rod I5. By means of a spring IS, the pressure member I3 is adapted to be urged toward the shield I2 and tube II.

The shield I2 has a depression I! formed thereurged by the spring jI6, when the shield and pressure members are in the nonj-moistening'positionof Fig. 3. The pressure member is secured in place on the rod I5 by means of a screw 22 and lock washer 23.

The moistening member II has a longitudinal opening 24 therein and a capillary slot 25. Said opening 24 and slot 25 are supplied with liquid of said capillary tube provides a film of liquid at the tube II, and that the pressure member I3 is spaced from the shield l2 to provide a guide opening through which the tape passes, while shielded from the moistening slot. The tape is unmoistened when received in this manner.

When the device is arranged according to the position of Fig. 4, the shield I2 is withdrawn to expose the slot 25, and the pressure member I3 is urged toward the slot by the spring I8. This I will effect engagement of the gummed surface of the tape with the slot 25, and when the tape is withdrawn, the gummed surface will be mois- 'tened.

By adjustment of the handle I8 through the length of the slot I9, the device may be set in either a moistening or non-moistening position.

The tape may be received from any desired source or tape issuing device such as indicated generally at 2 6.

in along one edge thereof, and is provided with a Having described the invention what is claimed is:

1. In a gummed tape moistening device, a moistening member having a liquid moistening surface disposed in the path of tape issued from a tape issuing device, a manually adjustable shield movable relative to the moistening surface of the moistening member to effect shielding or non shielding of said moistening surface, and a pressure member movable with the shield to urge the tape against the moistening surface of the moistening member when the shield is in a nonshielding position.

2. In a gummed tape moistening device, a moistening member having a liquid moistening surface disposed in the path of tape issued from a .tape issuing device, a manually adjustable shield to the moistening surface of the molstening mem her to effect shielding or non-shielding of saidmoistening surface, a pressure member movable relative to the moistening surface of the moistener member, and means to normally urge the pressure member against said abutment shoulders when the shield is in ashielding. position to provide a guide for the tape between the shield and pressure member, andto urge the pressure member toward the moistening surface to thereby urge the gummed surface of the tape against the moistening surface when the shield is in a nonshielding position.

4. In a gummed tape moistening device, a moistening member having a liquid moistening surface disposed in the path of tape issued from a tape issuing device, a manually adjustable shield movable relative to the-moistening surface of the moistening member to effect shielding or nonshielding of said moistening surface, a pressure member movable relative to the moistening surface and shield, and means to effect simultaneous movement-of the pressure member and shield, whereby, during shielding of the moistening memher, the pressure member and shield are spaced apart to form a guide through which the tape will move without effecting moistening, and during non-shielding'of the moistener, the pressure member will urge the tape against the moistening surface to efiect moistening of the tape.
